GAS MIXER.

Specification of Letters Patent.

Patented Feb. 21, 1922.

Application filed February 9, 1920. Serial No. 357,222.

To all whom it may concern:

Be it known that I, CARL A. PETERSON, subject of the King of Sweden, residing at Superior, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Gas Mixers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to gas mixers and has special reference to such a device used in connection with the gas supply of an internal combustion engine which is received through a manifold and feed pipe leading from a carburetor.

The principal object is to produce a simple and eiiicient device for assisting in the more thorough mixing and agitating of the gas intermediate of the manifold and the carbureter.

Other objects and advantages of the peculiar construction will appear in the further description of the invention.

I am aware that many different forms of both rotative and fixed devices have been employed for this purpose but believe that I have discovered a peculiarly shaped mixer for this purpose that will give exceptionally good results. In fact the same has been thoroughly tried out and proven by me to work admirably well.

In the accompanying drawings forming part of this application and in which like reference characters indicate like parts:

Fig. 1 is a top plan view of the mixing wheel and its support.

Fig. 2 is a vertical central sectional view through a carbureter and manifold connecting pipe with the mixer installed therein.

Fig. 3 is an elevation of the mixing wheel viewed at right angles to that shown in Fig. 2, and

Fig. 4 is an opposite view of the wheel and its mounting, to that shown in Fig. 1.

1 represents a comparatively thin fiat metal disc having diametrically opposed open ended slots 2 therein through which the bolts which hold the pipe connections to the carburetor pass when the disc is installed berior tween the flanged end of the pipe 3 and the carburetor discharge 4 and where it is securely held by said bolts when completely installed.

Through the center of the disc 1 is formed a circular opening the same size as the inteof the pipe 3 and spanning the opening is a narrow cross arm or web 5 which is preferably thicker than the disc and in the center of which is securely fixed the upstanding pin or arbor 6 upon which the mixing wheel is rotatably mounted.

The novel feature of this wheel is that it is a combined propelling and mixing wheel in that one or the lower end is formed into two opposed propeller like or spirally shaped blades 7 which terminate their spiral course approximately one third of the total length of the wheel from the opposite end and from such termination extend straight to the upper end of the wheel forming two opposed straight fan-like blades 8 which when rotated produce only centrifugal influence upon the gas as it passes after having imparted rotary motion to the wheel by contact with the spirally shaped portion thereof.

While it is hard to describe the resultant agitation to the column of gas by this combined motion of imparting power to the wheel and then being agitated by the latter, the same has been found to give good results and experiments with a different relative proportion of straight to spiral blades has given less efficient results.

The mixing wheel is preferably made as nearly as practical the full size of the inside diameter of the conducting pipe in which it is installed thus resulting in all of the gas passing through the pipe being acted upon or engaged by the wheel.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

1. A gas mixer of the class described comprising a suitable support and a one piece smooth surfaced elongated mixing wheel rotatably mounted upon the support, the portion of said wheel adjacent the support being of spiral form and the portion at the opposite end being fan shaped, said wheel restrai ht blades being a continuation of the 10 ceiving motion by the action of the gas, subspirfi blades and the latter receiving action stantially as described. by the motion of the gas being mixed.

2. A gas mixer of the class described com- In testimony whereof I hereunto aflix my prising a suitable support and a double signature in the presence of two witnesses.
